row across the toes. Consequently the toes of most grown 

 people are squeezed together, frequently overlapping. 

 The great toe naturally rests a little separated from its 

 neighbor, and almost in a straight line with the inner 

 side of the foot. If we make it turn in, its principal joint 

 stands out prominent, and from the pressure becomes 

 inflamed. A bunion is formed there. A corn is another 

 painful result of pressure. 



The foot is a much-enduring member, and is useful, 

 even though crippled. But grace and ease of movement 

 are constantly sacrificed, and numberless miseries in- 

 curred, for the sake of making the foot look small. 



Athletes and pedestrians long ago discovered the neces- 

 sity of a shoe which gives freedom to the foot. Such a 

 shoe is never tight. The heel (if any) is low and broad, 

 and directly under the heel of the foot. The sole is as 

 broad as the foot itself, and at least half an inch longer.
